:My invention relates .to elastic rbearings :iior v-eentrifugal:machines, as. tor example, cream separators,. andits purposes .-are,tomakewa bearingthatshall be simple and economicab in= eonstructionjandireliable and eflicient :in .operation, and in which athe springs, ifbroken n01 defective, :oan be 'readilyaa'nd inexpensively .replaced s by5 any one. :I attain these purposeszbyathezmeams shown in i theaccompanying i drawings, in -w.hi'ch a F igurel-is a-plan.
